Documentation
defaultBufSize :: BufSize Source #
The default buffer size (4,096 bytes).
freeBuffer :: Buffer -> IO () Source #
getStderrFD :: IO FD Source #
getStdoutFD :: IO FD Source #
Builders denote sequences of bytes.
They are Monoids where
mempty is the zero-length sequence and
mappend is concatenation, which runs in O(1).
Log message builder. Use (<>) to append two LogStr in O(1).
fromLogStr :: LogStr -> ByteString Source #
Converting LogStr to ByteString.
class ToLogStr msg where Source #
Types that can be converted to a LogStr. Instances for
types from the text library use a UTF-8 encoding. Instances
for numerical types use a decimal encoding.
